What to Do If You Have Cyanide in Your Industrial

2021-4-5 · Also known as oxidation, cyanide destruction is a process where a chemical oxidant (or other agent) is used to break down the carbon-nitrogen triple bond in WAD cyanides. This oxidation reaction forms cyanate (OCN – ), which is far less toxic than cyanide, and is less persistent in the environment.
